It’s not like he shut down someone else’s work. He stopped working on his own pet project. There’s nothing stopping you from picking it up and working on it. It’s publicly available. Insulting him seems juvenile and entitled. It’s not his job to supply people with this (literally, he’s not being paid for it). Even if you think he took a payout to stop working on it, or he was bullied into stopping (no support for either of these positions) it’s ok for an 18 year old to be concerned about threats from a company and it’s ok for them to take a payout for something they worked on. Again, no evidence for either, but neither of those scenarios would make it appropriate to insult him.
